Novel coupling between charge order and time-reversal-symmetry-breaking superconductivity
Quanxin Hu, Lingfeng Zhang, Yu Zheng +9
The interplay between charge-density waves (CDWs), which break translational symmetry, and spatially homogeneous superconductivity, which breaks global U(1) gauge symmetry, can giv…
Evidence of pseudogap and absence of spin magnetism in the time-reversal-symmetry-breaking state of BaKFeAs
Florian Bärtl, Nadia Stegani, Federico Caglieris +13
Muon-spin-rotation (SR) experiments and the observation of a spontaneous Nernst effect indicate time-reversal symmetry breaking (BTRS) at above the supercon…
Direct observation of quantum vortex fractionalization in multiband superconductors
Yu Zheng, Quanxin Hu, Haijiao Ji +13
Magnetic field is expelled from a superconductor, unless it forms quantum vortices, consisting of a core singularity with current circulating around it. The London quantization con…
Crystal structure, properties and pressure-induced insulator-metal transition in layered kagome chalcogenides
Hong Du, Yu Zheng, Cuiying Pei +3
Layered materials with kagome lattice have attracted a lot of attention due to the presence of nontrivial topological bands and correlated electronic states with tunability. In thi…
Avoided metallicity in a hole-doped Mott insulator on a triangular lattice
Chi Ming Yim, Gesa-R. Siemann, Srdjan Stavrić +9
Doping of a Mott insulator gives rise to a wide variety of exotic emergent states, from high-temperature superconductivity to charge, spin, and orbital orders. The physics underpin…
Calorimetric evidence for two phase transitions in BaKFeAs with fermion pairing and quadrupling states
Ilya Shipulin, Nadia Stegani, Ilaria Maccari +9
Theoretically, materials that break multiple symmetries allow, under certain conditions, the formation of four-fermion condensates above the superconducting critical temperature. S…
Magnetic-Field Tunable Intertwined Checkerboard Charge Order and Nematicity in the Surface Layer of SrRuO
Carolina A. Marques, Luke C. Rhodes, Rosalba Fittipaldi +7
In strongly correlated electron materials, the electronic, spin, and charge degrees of freedom are closely intertwined. This often leads to the stabilization of emergent orders tha…
Discovery of a strain-stabilised smectic electronic order in LiFeAs
Chi Ming Yim, Christopher Trainer, Ramakrishna Aluru +5
In many high temperature superconductors, small orthorhombic distortions of the lattice structure result in surprisingly large symmetry breaking of the electronic states and macros…
